There is a boost leak on my 2001 A4 Quattro 1.8 turbo Avant. I checked the hose that leads from the Intercooler to the throttle body inlet and it seems to have a few small cracks. I would like to replace this hose myself but I am having trouble finding the part. Does anyone know the part number and / or an online store to buy the item at? Is there any aftermarket hoses I could get? If so where could I purchase the aftermarket item from?

I am new to this forum so please bare with me if I have made any newbie mistakes.

 

Welcome to the forum and the joys of owning Audis.

No newbie mistakes, but you will find a wealth of information in the archives and in the FAQ and links.

Who has their part list out to help this gentleman?

 

Well it looks as if I am going to the dealership for this part. Hope the price isn't too bad, I'll install it myself.

 

I think that is just regular braided hose the part # is n 0203535

 

i just went to autozone for mine

 

how did you discover the boost leak, boost gague?

 

You can hear it when you go WOT

 

I can't seem to find any sites that recognize the part number 0203535 . Am I entering the part number wrong (0203535 is exactly as I entered it)? The Dealer wants $86.05 USD for the hose!

 

The Part number I got from my Audi dealer is 4b0-145-838 but that doesn't generate any hits for any online stores. Sorry for posting repetedly.
